Effect of electromagnetic fields from renewable energy subsea power cables on righting reflex and physiological response of coastal invertebrates.
This study examined whether electromagnetic fields (EMF) similar to those from offshore renewable subsea export cables affect coastal invertebrates. It simulated a 500 μT EMF and measured righting reflex and selected physiological markers in four species. The authors report no significant behavioural or physiological differences under the tested conditions.
Key points
- The study addresses potential environmental impacts of EMF from subsea power cables associated with offshore renewables.
- An EMF level of 500 μT was simulated to represent an export cable over rocky shore where burial may not be possible.
- Four coastal invertebrates were assessed: common starfish, edible sea urchin, velvet crab, and common periwinkle.
- Behavioural response was evaluated using righting reflex.
- Physiological measures included refractive index of haemolymph/coelomic fluid and total haemocyte/coelomocyte counts.
- No significant differences were found in the measured behavioural or physiological outcomes under exposure.
